I-pods don't have lots of output power, but if it's putting out more than your keyboard, then the problem is with the keyboard's output power. I suspect there is nothing wrong with the Z-5500.

A work-around for this may to be to fire your keyboard through a small mixer, such as the Alesis 6FX, or something similar, which would boost your keyboard's output.

Now, if you're trying to compete for volume with a band using a big PA system, it's not gonna' happen. When you bring your volume up, they'll crank up their volume, and by the end of the night everyone will have ringing in their ears--including your audience.

Also, keep in mind that speaker position is critical, even with standard or conventional PA systems. If your Z-5500 speakers are sitting on a table, or worst yet, on the floor, you will not get much out of the satellites. They must be positioned at least 5 feet above the floor in order to be effective.

If the Z-5500 doesn't provide sufficient punch for your type of performances using this type of setup, then it would probably be a good idea to take it back for a refund and go with something else. That's why I tell everyone to purchase the system at a location that has a liberal return policy.

Good Luck, and I sincerely hope everything works out for you.
